One of my favorite most versatile melee weapons in Darktide. You can parry literally everything in the game including overheads from Crushers and boss strikes (though I would still combine with dodge as it gobbles up stamina.) Throw in 5 dodges and a generous dodge distance with a ton of stamina and you have a very mobile and effective sword. Columnus can shred almost anything at a safe distance, particularly after procking ranged specialist.
